Skip Fusion With Sacral-Alar-Iliac Screw Fixation for Pelvic Ring and Lumbar Fractures: A Case Report.

Pelvic ring fractures are associated with high-energy trauma and high mortality owing to critical blood loss and concomitant injuries. If there is a concurrent lumbar fracture, the postoperative range of motion will be limited owing to the increased fusion range. Here, we report a case in which skip fusion with sacral-alar-iliac screw fixation was effective as a minimally invasive procedure for treating pelvic ring and lumbar fractures.

日本における完全頚髄損傷の疫学

工藤大輔, 宮腰尚久

The Japanese Journal of Rehabilitation Medicine ( 公益社団法人日本リハビリテーション医学会 ) 60 ( 12 ) 1038 - 1043 2023年12月

1990年代の新宮らの調査以来となる外傷性脊髄損傷の全国調査が実施された．2018年の脊髄損傷の推定発生率は100万人あたり49人，平均年齢66.5歳，受傷原因は平地転倒が最多（38.6％），機能障害はFrankel Dが最多（46.3％）であった．生産年齢（15～64歳）における完全頚髄損傷は，135名の登録があり，年齢中央値51歳で，全体の3.3％，完全頚髄損傷の34.0％を占めていた．生産年齢では，非生産年齢と比較し，交通事故（p＝0.005），重量物落下・下敷き（p＝0.008），スポーツ（p＜0.001）による受傷が多く，非生産年齢では平地転倒（p＜0.001）による受傷が多かった．

Risser sign grade 4の思春期特発性側弯症におけるCobb角進行と危険因子の検討

若林玲奈, 本郷道生, 三澤晶子, 木村竜太, 工藤大輔, 島田洋一, 宮腰尚久

Journal of Spine Research ( 一般社団法人日本脊椎脊髄病学会 ) 14 ( 11 ) 1377 - 1382 2023年11月

はじめに：思春期特発性側弯に対する装具治療は，一般に骨成熟が終盤と評価されるRisser sign grade 4以上には積極的推奨はされていない．しかし，Risser sign grade 4でもCobb角が進行する症例をしばしば経験する．対象と方法：対象は2016年から2020年に当院を初診し，Risser sign grade 4を呈する思春期特発性側弯症のうち1年以上経過観察した42例であった．Cobb角の変化，患者背景，身体所見，放射線学的評価を，進行群と非進行群に分け比較検討した．結果：進行群8例，非進行群34例で，進行群ではCobb角が初診時28.7°が経過観察時35.8°となり，平均7.1°増加した．初潮から初診までの経過期間は非進行群24.2ヶ月に対し進行群9.7ヶ月と有意に短く（P=0.003），身長変化は非進行群が1.8 cm増加したのに対し，進行群が2.9 cm増加と有意に大きかった（P=0.02）．その他では差を認めなかった．結語：Risser sign grade 4の思春期特発性側弯症の約2割で側弯の進行を認めた．進行群では，初潮から初診までの経過期間が短く，身長の伸びが大きかった．初潮から初診までの経過期間と身長変化により，進行が危惧される場合は装具治療も考慮する必要がある．

秋田県における側弯症検診の現状と課題

三澤晶子, 本郷道生, 工藤大輔, 若林玲奈, 木村竜太, 島田洋一, 宮腰尚久

Journal of Spine Research ( 一般社団法人日本脊椎脊髄病学会 ) 14 ( 11 ) 1366 - 1371 2023年11月

はじめに：本県では1984年からモアレ法による学校検診を行っており，運動器検診開始後も継続している．今回，秋田市教育委員会のデータ提供により，運動器検診の結果とモアレ法による側弯症検診の結果を比較した．対象と方法：2017～2020年度に運動器検診で脊柱に所見ありとされ二次検診を受診した1,442例と，モアレ検診で所見ありとして二次検診を受診した474例を対象とし，X線撮影によるCobb角10°以上の陽性率を算出した．結果：陽性適中率は運動器検診で39%，モアレ検診では60%であった．中学生の陽性適中率に限ると，運動器検診で57%とモアレ検診と同程度だったが，診断された13%が運動器検診で新規に陽性，87%が継続して陽性であり，大多数の症例がモアレ検診で側弯症の診断を受けていた．結語：本研究の結果から，改めて運動器検診との対比においてモアレ検診の有用性が明らかになった．検診を進めるにあたり，検診後のフォローアップ体制の充実も必要と考えられた．また，検診結果のフィードバックのため，個人情報保護の問題等解決に向け，検診の発展には教育委員会や医師会への働きかけと連携が必要である．

Case reports in orthopedics 2020 8816598 - 8816598 2020年

INTRODUCTION: An arachnoid web (AW) is a relatively rare disease and shows clinical symptoms and radiological findings similar to those of an arachnoid cyst (AC) or spinal cord herniation (SCH). Since the operative procedures for an AW are generally different from those intrathecal disorders, correct preoperative differential diagnosis is important. The purposes of this study were to report the usefulness of magnetic resonance imaging (MRI) and computed tomography (CT) myelography for diagnosing AW and to show the histological findings and clinical results. Case Description. Two patients, a 79-year-old man and a 43-year-old woman, are presented. The primary diagnoses were AC with ossification of the ligamentum flavum and epidural hematoma, respectively, in previous hospitals. They were finally diagnosed by the characteristic MRI and CT myelogram finding called the "scalpel sign." Histological findings showed epithelial cells and fibrous tissue derived from arachnoid tissues and microcalcifications. After surgery, the scalpel sign has vanished, and aggravation of their symptoms was prevented. CONCLUSION: An AW is refractory, but early detection by MRI and CT myelography and early treatment improve outcomes after surgery.

Miyakoshi Naohisa, Masutani Norimitsu, Kasukawa Yuji, Kudo Daisuke, Saito Kimio, Matsunaga Toshiki, Shimada Yoichi

Progress in Rehabilitation Medicine ( 公益社団法人日本リハビリテーション医学会 ) 5 ( 0 ) n/a 2020年

Objectives: Previous studies have suggested that the effects of vitamin D in preventing osteoporotic fractures result in part from its influence on fall prevention. However, the effects of vitamin D on dynamic balance as a contributor to fall prevention have not been fully evaluated. Moreover, few studies have compared the effects of native and active forms of vitamin D. The objective of this preliminary randomized prospective study was to compare the effects of native vitamin D and eldecalcitol on muscular strength and dynamic balance in postmenopausal patients undergoing denosumab treatment for osteoporosis.Methods: A total of 30 women with postmenopausal osteoporosis were randomly assigned to a native D group (administered denosumab and native vitamin D with calcium) or an ELD group (administered denosumab and eldecalcitol) and were followed up for 6 months. The following parameters were compared: the strengths of the back extensor and lower extremity muscles; static balance evaluated using the one-leg standing test; and dynamic balance evaluated using the 10-m walk test, the functional reach test, the timed up and go test, and the total length of the trajectory of the center of gravity (LNG) measured using a dynamic sitting balance measurement device.Results: Compared to baseline measurements, back extensor and knee extensor strengths had significantly increased after 6 months of treatment in the native D group (P<0.05) but not in the ELD group. In contrast, LNG significantly improved in both groups after 6 months (P<0.05). No significant differences between the two groups were seen in any of these measured parameters after treatment.Conclusions: Both native vitamin D + denosumab and eldecalcitol + denosumab were effective for improving dynamic sitting balance in postmenopausal women with osteoporosis.
